Ratings and Reviews
Fantastic no-frills toolkit for all-around backcountry navigation
The broad range of layers provided, plus the ability to dynamically “layer layers” and cache maps for offline use, makes this my go-to navigation resource for backcountry planning and navigation. Includes super detailed place name and trail/road info missing from many other map apps. Accurate slope angle shading is a literal lifesaver during avalanche season and weekly satellite data is awesome for estimating snow cover. Only wish that the NAIP satellite data layer came with a little more detail - I usually combine with Google Earth when planning trips for better landform visualization.
Great information but the app is lacking
1st off, I love CalTopo. I have been using the web version for years and have been a paid member for a while now. The amount of information available in CalTopo is unmatched in my opinion. The only problem that I have with the service is with the interface, especially the app. It is quite slow to load data and seems very buggy. I have to constantly force shut down the app and occasionally restart my phone for it to load things more quickly and properly. It got so annoying that I paid for Gaia to test it out because their app looks great, is quick and responsive pulling data up almost immediately. Unfortunately, while they have most of the data CalTopo has they don’t have all of it so I continue to use CalTopo. I’m really hoping they will get things sorted out in the future. It’s still worth the money bury very frustrating to use at times.
Best maps anywhere, horribly buggy app
CalTopo has all of the Forest Service maps which seem not to really be available elsewhere online. They are invaluable. Their web interface is great. However the iOS app is incredibly buggy. Map tiles go missing when you scroll despite having previously downloaded them, the FS Topo 2016 maps appear black and are not really useful versus the way they do appear on the website, the download interface has issues, the map periodically crashes, etc. It would be the best outdoors mapping app ever if they just fixed these navigation, map scrolling/zoom/management/download issues. I dare not go into the wilds alone with this as my sole map app for this reason (have had cases where I am is a tile that won’t render at all), but when it does work, it’s great.
